SP Switch environment (MAP 0600)

Step 0600-025

You have a PS1Fail problem

1.Replace power supply card PS1.

2.Reinstall the SPS front panel assembly, being careful to align the guide pins on the P1 to the inner chassis cup guide.

3.Replug the power cable (J1) and supervisor cable (J2) to the rear of the assembly.

4.Put the circuit breaker in the On (`1') position.

5.Does the PS1Fail condition still exist?

vIf yes, go to ªStep 0600-026º.

vIf no, go to ªStep 0600-017º on page 1-10.

Step 0600-026

After replacing the power supply card you still have a PSxFail condition.

1.Put the circuit breaker in the Off (`0') position.

2.Remove the power cable (J1) and supervisor cable (J2) from the rear of the SP Switch.

3.Remove the front panel assembly.

4.Replace the supervisor card.

5.Reinstall the SPS front panel assembly, being careful to align the guide pins on the P1 to the inner chassis cup guide.

6.Replug the power cable (J1) and supervisor cable (J2) to the rear of the assembly.

7.Put the circuit breaker in the On (`1') position.

8.Does the PSxFail condition still exist? v If yes:

a.Replace the SP Switch inner chassis assembly.

b.Go to ªStep 0600-017º on page 1-10.

vIf no, go to ªStep 0600-017º on page 1-10.

Step 0600-027

You have a PSFuseGood problem.

1.Remove power supply PS1 (refer to ªRemoving the switch power cardsº on page 4-6).

2.Reinstall the SPS front panel assembly, being careful to align the guide pins on the P1 connector to the inner chassis.

3.Replug the power cable (J1) and supervisor cable (J2) at the rear of the assembly.

4.Put the circuit breaker in the On (`1') position.

5.Does the failure condition still exist?

v If yes, go to ªStep 0600-029º on page 1-13.

vIf no, go to ªStep 0600-028º.

Step 0600-028

You have a PSFuseGood problem that went away when you removed power supply PS1.

1.Put the circuit breaker in the Off (`0') position.

2.Remove power cable (J1) and supervisor cable (J2) from the rear of the SP Switch.

3.Remove the front panel assembly.

4.Replace power supply PS1.

5.Take the switch out of the service position (refer to ªService position proceduresº on page 3-9).

6.Go to ªStep 0600-017º on page 1-10.

RS/6000 SP specifications

The IBM RS/6000 SP (Scalable Power) is a high-performance computing system that was developed in the early 1990s and has since become a significant player in the realm of supercomputing and enterprise solutions. Designed primarily for scientific, engineering, and complex data analysis tasks, the RS/6000 SP provides powerful processing capabilities, enhanced scalability, and features to support demanding applications.

One of the key characteristics of the RS/6000 SP is its modular architecture, which allows for the addition of multiple nodes. Each node is based on IBM's Power architecture, leveraging the RISC (Reduced Instruction Set Computing) design to achieve high throughput and efficiency. The system can support configurations ranging from a few nodes to hundreds, enabling organizations to scale their computational power as needed based on workload requirements.

The RS/6000 SP employs advanced interconnect technologies, most notably the SP Switch, which ensures high-speed communication between nodes. This interconnect allows for seamless data transfer, ensuring that the system can handle large datasets and complex computations without bottlenecks. The SP's ability to deliver concurrent processing capabilities makes it ideal for parallel computing tasks, including simulations, modeling, and large-scale computations.

In terms of software, the RS/6000 SP was equipped with AIX, IBM's version of the UNIX operating system, which provides a stable and secure environment for enterprise applications. Furthermore, the system supports a vast array of programming languages and tools, including Fortran, C, and C++, along with libraries and frameworks designed for high-performance computing. This compatibility allows developers to optimize their applications to fully utilize the underlying hardware.

Another notable feature of the RS/6000 SP is its extensive support for various workloads, including database management, multi-user applications, and graphical processing. The system was equipped with high-performance graphics capabilities, making it suitable for tasks that require intensive visualization, such as computer-aided design (CAD) and scientific visualization.

Overall, the IBM RS/6000 SP has solidified its role in the high-performance computing landscape, combining advanced technologies, robust scalability, and flexibility to meet the unique demands of research and enterprise environments. Its legacy continues to influence modern computing architectures, embodying IBM’s commitment to innovation and performance in the pursuit of complex problem-solving capabilities.
